I think some added features to home bases could be added for additional defense and offense when the enemy captures all bases. This could even tie into farming/spawn killing as far as giving your team a fighting chance.
Base defense turrets:
I’m sure this has been brought up multiple times but I had a few ideas.
Have 2 anti vehicle turrets sitting in the outside corner of bases that only activate when your bases defenses are down. Make them tough with it taking a few shots from a tank to destroy?
Have a small one mounted on the back of the base with weak armor as a last resort.
The last one would be 4 medium size turrets built into the front of the base where you can actually use them to attack the enemy while the rest of the team attacks below. Create a commendation for getting kills with it as well as for destroying an enemy one.
Granted I don’t know how to implement such a thing while keeping it balanced, but it might be a nice feature that could hinder some of the farming that happens on warzone?
